invention relates to improvements in twoway envelopes, and the object of the 'invention'is to devise an envelope of this type inwhijch the f act ofr opening the closed envelope by therecipient "at its forwarding destination Vwill form the closing flap on the bodyl of the envelope to automatically convert it to a return envelopeand in the casewherea "letter or circular sheet is formed integral vwith the l envelope will simultaneously ,sever the letter sheet from theenvelope as the v.envelope is opened and the return flap formed vand which, byfthe closing of the return envelope,

will automatically indicate the change in direction of transit` of the letter or circular eliminat-v ing the necessity of re-adciressinge the envelope, and in which, in the Iirstabove referred to case of forming the forwarding and return `venvelope in one blank, both envelopes are printed in ione operation,vall the printing matter being on'one face of the blank andinthe secondabove re-v ferred to case ofA forming the forwardingr envelope, return envelope, circularV and an attached cheque al1 in one blank, all may be printed in Aone operation which, under ordinary circumstances, require four separate' operations thus greatly reducing vthe. cost of production,V and it consists essentially of the arrangement and construction of parts as hereinafter rmore'particularly explained.

toa Yside opening envelope. f In these'guresf'lfs is the 'front wall 'fof the envelopeprrovidedlwith a `space VIlfor the addressor and a space20for the addressee' Separated, bv. the rear wall of Vthe-"env el` 23 and from the end of the front wall I8, and'24 lines so that whenythe stitching inthe tab 28 Yis" pulled the portions 24, 29,' 30 and 3l arer detached so as to form a return closing ap 32 which covers .the forwarding indications "Fro1n and From inposition opposite the spacesY |9` y and for the addressor and addressee.

' This form ofy enveloper may also'be modified to 20 include a letter or circular sheetformed integr therewith. l Y e In Figs. 6 to l1 I have illustrated a form of envelope which opens Yat the top and which'has a circular or letter sheet formed integral therewith. k f

In these figures 33 is the front rwallv and 34 the .rear wall. The front wall is provided with end iiaps 35 and 36 foldable on the crease lines 35x and I 36X against the rear wall 341'v when folded on the crease line 3l. e f Y 38 and 39' are two portions of a circular connected on ,the crease line 43 to the rear wallof i the envelope and together on'the crease'line 4I. AlthoughgIhave only shown two portions 38 and 39 it will,of course, be understood that any number of portions suitably folded to fit theenvelope maybe provided. is a Vtabiand G3 Yaline of stitching extending through'the tab andcoincid- Y' n ing withthe creaseline Lil. i

In closing the envelope the portionse'3`9,;38 and 34 are folded up on their respective crease lines and the envelope closed by rneansof the-naps 35 I and 36 'which are gummed to adhere to the back .wall as indicated in Fig. 7. 'I'he under-surface of the blank, between the crease line 40 and dotted line/ aux, is gummed. When it is desired to open Ythe'envelope the thread in the tab 42 'is gripped and the envelope ripped along the line 4D thereby j separating they portions 38 and 39,. from the enf I velope leaving the `gurnnfied.portion between 40 and QSE-projecting above .the-upper edge of vthe front wall as indicated in Fig.'l0"so that after the detached letter is withdrawn' from'the envelope` it y n 4 may be folded overthev upper edge` ofthe frontV f wall 33 and gummed down for the return so tor and To and brings the return indications To Y cover the forwarding indications From and To and placing the return indications To and From adjacent to the spaces for the addressor and addressee in the same manner as that previously described. In this form it may be for- Warded as a circular, a one cent stamp being placed in the stamp space 43 and returned 'as a letter, a three cent stamp being placed in the stamp space 44 and, therefore, adaptable for returning of a cheque;

From this description it will be seen that I have deviseda two-way envelope which is simple 'in construction, kreadily opened and by the act ,of` l opening converted into a return envelope elimi' nating any, necessity for re-addressing the envelope for its return and in the case where a letterV or circular sheet is formed integral with the envelope blank, such sheet is. also s everedfrom the envelope by the act of opening the forwarded envelope and further, in the `forms illustrated'in {igs. liuto 5lbotb. the forwarding rand return en- ;velopernay be printed vin one operation which usually involves two operations, the forwarding l landreturnenvelope' being previously printed by separate operations, and in the orns illustrated 1'ig.8theH forwarding envelope,`return envelope, circularlandcheque, which usually require operations to print, ,may all be printed in one vfold between thewap'andits extension'. l

operation as in each of these cases the matter is all printed on one face of the blank.

What I claim as my invention is:-

1. In a two-way envelope, the front and rear wall portion of an envelope body open along one edge, a severable strip forming part of the front wall and one edge of the opening, a severable flap extending from the other edge of the opening and scalable against the severable flap for forward transit, and a scalable portion forming part of the rear Wall andv from which the aforesaid flap is severable and sealable against the' front wall of the envelope for return transit after the severable portion and severable flap are severed. 1,2.,In atwoway envelope, a blank folded and secured to form a permanent envelope 'the front Wall of whichisprovided with a direction indication adjacent its edge, a sealing flapr formed by the rear wall of the envelope extending above the edge of the fro-nt wall of the Venvelope when in `conditionvfor return transit and foldable over lsuch edge t'o conceal `thev forwarding direction indication, an extension to the sealing ap' foldable to engage the front wall of the envelope for forward transit', and a'line of perforations .on the line of PHLIP zAxlDlii/Is;
